The 2 men rest their hands on a stone in the centre of the painting.
This stone is a symbol of their strong friendship.

Endymion Porter was a significant English diplomat who served as secretary to the Duke of Buckingham.
He was also responsible for buying artworks for the collection of King Charles the First of England.
Porter played a vital role in promoting and supporting the work of the painter Van Dyck.
Thanks to the efforts of Porter, van Dyck was appointed as the official portrait painter to Charles the First.
In the 17th century, painters depicted the social status of people in their paintings.
Porter is a diplomat in this painting and has a more important social status than Van Dyck.
For this reason, Van Dyck painted Porter taller and dressed in a bright colour to make him more visible in the painting.
